    Import Encrypted Logical Units

    Problem solved using napp-it! Unlocked the encrypted filesystem by clicking "locked" on the ZFS filesystem list and choosing L1:L1 keysource to unlock. Then went to Comstar, Import LU and it made the logical unit available again. Added a view and rescanned storage on hosts using that LUN. All...

    Import Encrypted Logical Units

    Thanks for your response. Encrypted logical units were created with napp-it as file-based LU’s under encrypted ZFS filesystem /pool0/efs1. Tried ‘stmfadm import-lu’ after the import, but this error comes up: # stmfadm import-lu /pool0/efs1/elu01 stmfadm: meta file error Pool disk usage is...

    Import Encrypted Logical Units

    In the example /pool0/efs1 is the mount point for the encrypted filesystem. Possibly the mount is missing? That would explain why logical units are not listed in ‘ls’. Looked at ZFS docs, but couldn’t find mount options for encrypted objects.

    Import Encrypted Logical Units

    I moved a ZFS pool to another server. Pool imported with no errors using # zpool import pool0 pool0 contains both encrypted and unencrypted logical units. Encryption keys were restored to /local/keydata on the new server (plus a copy on another location). Unencrypted LU's were imported...

    ZFS with Broadcom/LSI 3108 in JBOD mode

    Thanks for your responses. I configured the BroadCom 3108 in JBOD mode with single disks and no RAID. ZFS sees the individual drives. Created a pool with 4 mirrors and configured an iSCSI LUN as storage for 2 low activity VMs. It seems operational so far with those workloads. Will report if any...

    ZFS with Broadcom/LSI 3108 in JBOD mode

    At a remote location we'll need to deploy a ZFS storage server using an OmniOS VM with napp-it over VMware ESXi. The only available server there has a SuperMicro X10DRH-CT motherboard with an onboard Broadcom 3108. In normal circumstances we would add a Broadcom 3008 to that motherboard for ZFS...

    ZFS and VMFS6 Space Reclamation

    There is an option to disable VMFS6 automatic space reclamation from the vSphere web client, e.g. by selecting the datastore then Configure, General, Space Reclamation. See the attached screenshot. That helps with Solaris ZFS deployments that can't go back to VMFS5.

    ZFS and VMFS6 Space Reclamation

    VAAI unmap is specific to iSCSI datastores, but other VAAI primitives and hardware acceleration also apply to NFS datastores. https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vmware-nfs-best-practices-white-paper-en-new.pdf Hardware Acceleration on NAS Devices...

    ZFS and VMFS6 Space Reclamation

    Contacted VMware Support on this issue. It turns out that the degradation is partly due to using a storage server that does not support VAAI unmap and partly due to a VMware bug. VMFS space reclamation is implemented using VAAI unmap. It will not work with storage servers that don't implement...

    ZFS and VMFS6 Space Reclamation

    VMware implemented a new file system type VMFS6 available with ESXi 6.5 and 6.7. One of its new features is automatic space reclamation. Space Reclamation Requests from VMFS Datastores The default setting on new datastores with VMFS6 is a reclamation priority of "Low" with maximum bandwidth of...

    Occasional OmniOS iSCSI disconnect from VMware

    Gea, Thanks for your suggestions. There are ten HGST He8 8TB SATA drives on a mirrored (RAID10) pool. Looked at %w and %b on iostat for several iterations, but didn't see significant differences. # iostat -xn 1 2 extended device statistics r/s w/s kr/s kw/s wait...
